摘要根据国际中性束注入器诊断技术的发展趋势，计划为聚变技术综合研究装置负离子注入器样机设计一套多通道朗缪尔静电探针诊断系统。探针安装在中性束装置的不同部件上，以获得等离子体参数。由于探针处于不同的位置和不同的电位，传统的基于公共资源的以太网协议的数据采集系统无法满足实验中电位隔离和高时间分辨率同步采集的要求。提出了一种基于时间敏感网络协议光纤网络的数据采集处理系统，解决了不同电位信号的高时间分辨率同步采集，实现数据处理。为射频负离子源等离子体特性的研究提供了技术手段。
Abstract According to the development trend of the international neutral beam injector diagnostic technology, it is planned to design a multichannel Langmuir electrostatic probe diagnostic system for the Comprehensive Research Facility for Fusion Technology negative-ion-based beam injector prototype. The probes are installed at different components of the neutral beam device to obtain plasma parameters. As the probes are at different positions and different potentials, conventional data acquisition systems, which are based on the traditional Ethernet protocol in publicly available resources, cannot meet the requirements of potential isolation and synchronous acquisition with high time resolution in the experiment. A data acquisition and processing system that is based on the fiber optic network of the Time Sensitive Networking protocol is put forward that solves the synchronous acquisition of signals at different potentials with high time resolution to achieve data processing. It provides the technical means for the study of plasma characteristics of the radio frequency negative ion source.
